does it die upon start up? idling? driving down the road? all of the above? mostly likely CPS camshaft position sensor. they are known to fail on the 7.3

Yeah, need a little more info on the symptoms, like how often, and what was going on when it does it, and how hard was it to get started again. Did you happen to check codes? Did it seem to happen more when the truck was facing up hill?

it dies mainly after warms up, some times it starts right up and other times its hard to start. I've changed the cps and the irp, but really not a name brand.i notice it is taking a little longer to start up.
